SULFUR HEXAFLUORIDE- After the fire, proceed rapidly with cleaning of surfaces exposed to the fumes in order to limitequipment damage.6. ACCIDENTAL RELEASE MEASURES6.1. Personal precautions- Refer to protective measures listed in sections 7 and 8.- Approach from upwind.- Suppress (knock down) gases/vapours/mists with a water spray jet.- Avoid spraying the leak source.- Try to re-position leaking containers, to have the leak in the gaseous phase.- Vapours are heavier than air and can cause suffocation by reducing oxygen available for breathing.- Prevent further leakage or spillage if safe to do so.- Keep away from open flames, hot surfaces and sources of ignition.- Keep away from incompatible products6.2. Environmental precautions- Should not be released into the environment.6.3. Methods for cleaning up- Allow to evaporate.- Prevent product from entering drains.7. HANDLING AND STORAGE7.1. Handling- Used in closed system- Use only in well-ventilated areas.- Use only equipment and materials which are compatible with the product.- Prevent product vapours decomposition from contacting hot spots.- Prevent product vapours decomposition from electric arc action (welding).- Keep away from Incompatible products.7.2. Storage- Keep in a cool, well-ventilated place.- Keep only in the original container at a temperature not exceeding 40 °C.- Store in a receptacle equipped with a vent.- Store in upright position only.7.3. Specific use(s)- For further information, please contact: Supplier7.4. Packaging material- Steel drum7.5. Other information- Refer to protective measures listed in sections 7 and 8.- Keep away from heat/sparks/open flames/hot surfaces. - No smoking.8. EXPOSURE CONTROLS/PERSONAL PROTECTION8.1.
